Why do sugar and salt dissolve in water but not in oil? Why is water considered a good solvent? Class 8

Why do sugar and salt dissolve in water but not in oil? Why is water considered a good solvent? Class 8

Answer:

  1. Water is polar (has charged ends), so it attracts sugar and salt, which are also made of charged particles.
  2. Oil is non-polar, so it doesn't mix well with charged substances.
  3. Water is a good solvent because it can dissolve many substances due to its polarity.
